(57) The invention is concerned with air deflectors (1) for vehicles which, in use, serve
to decrease the resistance to movement of the vehicle through the air and, in particular,
with air deflectors of the self-inflatable type and made of flexible, substantially
air impervious sheet material shaped to provide, in the operative condition, a forwardly
located air inlet communicating, through a substantially dome-shaped region, with
a skirt (11) portion operatively rearwardly located. The air deflectors have means
(4, 5, 6, 7) for holding the air inlet (3) forwardly of the front (9) of a vehicle,
in use; with an operatively rear part of said skirt portion (11) being adapted to
be located over a front region of the roof and sidewalls of a vehicle to which the
deflector is fitted said part of the skirt region having a peripheral tension resisting,
optionally integral, strap formation (12) for holding said part of the skirt in position
on a roof and side wall section of a vehicle.
